Mei has 60 milliliters of a solution that is 35% nitric acid. how many milliliters of nitric acid does the solution contain?

21 milliliters of nitric acid.

Step-by-step explanation:

Given:

Volume of the solution is,

Percentage of nitric acid in the solution is 35 % of

Therefore, volume of nitric acid in the solution is =

Hence, the solution contain 21 milliliters of nitric acid.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
